Lord Dharma Shastha is also consecrated with equal importance. The consecration of Sree Rama is believed to have been made by Sage Agasthya. The temple pond here is believed to have been the sage's sacrificial pit. Lord Sree Rama is consecrated as he appeared before Khara with the crescent moon on his head, indicating the Shaivite presence. He is depicted with four arms and matted hair. There is an ancient banyan tree in the temple compound, more which is mentioned in the Thottam Pattu, which mentions 108 Ayappa temples in Kerala. This is also the only temple with the consecration of Hanuman. Ganapathy, Bhagavathy, Dakshinamoorthy, Sasathavu, Hanuman, Nagayakshy and Rakshass are the subordinate deities. The temple belonged to 4 brahmin families. With the land ceiling act in force, they found it difficult to run the temple. It was taken over by the Ayyappa Seva Sangham, who left it with the village officer. The local devotees made a committee under Thrikkalathoor Sree Ramaswamy Temple Seva Samithy and took over the management of the temple. The temple is famous for having conducted Archana with the three Vedas. The annual festival is celebrated for eight days to end on the day of the star Thiruvonam in the month of Makaram.
